Great hypotheticals of our time

What’s so wrong with space billboards? Why is the default “natural” view of the sky so preferable to a sky with some billboards in it?If the moon naturally, coincidentally had a Pizza Hut logo on itinstead of a “man in the moon” face, environmentalists would clamor to preserve it. Why are designs that are an accident of nature so preferable to advertisements which are, after all, designed specifically to please humans so they’ll buy things?
